Members of the family Poraniidae have a moderately well-developed row of marginal plates forming a distinct margin along the edge of both disc and arms. The aboral surface is covered with thick, naked skin, free from spines or pedicellariae but with scattered groups of papulae. There are no papulae or pedicellariae on the oral surface and the tube feet are always in two series.[2]
